St. Lukes Detention Basin (W14150704)

The City of Sacramento is initiating the St. Lukes Detention Basin project (W14150704) to construct a new stormwater detention basin on an undeveloped parcel at 7595 Center Parkway, Sacramento, California. The project involves the creation of an unlined basin approximately 13 feet deep with 3:1 side slopes, featuring a concrete access ramp and a concrete low-flow swale. To manage water flow, the system will include a new 36-inch conveyance pipe connected to a 7-foot by 10-foot vault in Center Parkway, equipped with an adjustable weir to divert water during critical heights and a one-way flap gate for return flow into the existing system. The basin must maintain a minimum five-foot setback from adjacent property fences. Site improvements include a six-foot-tall perimeter fence around the basin, a wrought iron fence at the property entrance with a rolling gate and asphalt driveway, and a gravel access road connecting the entrance to the basin fencing. The project is classified under NAICS code 237990 and has been deemed exempt under CEQA Section 15303 as it consists of small facility construction and utility extensions. Administration is handled by the City of Sacramento Department of Utilities, with key points of contact including Senior Engineer Gary Gulseth and Senior Planner Charles Tschudin.
